Abstract
The utility model discloses the hydraulic control mechanism of a hand-held mining rig, which comprises an annular casing, a feeding end cap, a compensating side board, a feeding control valve and an operating grip. The feeding end cap and the operating grip are fixed on the annular casing, and the feeding end cap and the compensating side board are fixed together. An annular distributing pore passage is formed between the end cap and the compensating side board, and a feeding pore passage is arranged on the compensating side board along the annular distributing pore passage. The feeding pore passage connects with the working chamber of a drill motor, and the oil scavenge cavity of the drill motor connects with the oilout pore passage arranged on the other side of the compensating side board. The feeding end cap is provided with the feeding control valve connected with the feeding conduit, and the operating grip controls the feeding control valve via the lever mechanism connected with the operating grip. The hydraulic control mechanism of a hand-held mining rig can reduce enormous connecting elements, greatly reduces the size and the weight of the rig and simultaneously realizes the steady regulation on the swiveling speed of the rig.
Description
Technical field
The utility model relates to a kind of hydraulic drill rig, particularly a kind of hand-held mining-drilling machine hydraulic control.
Background technology
Hand-held mining-drilling machine commonly used at present, because it is reasonable inadequately aspect structure design, and be subjected to the restriction of hydraulic motor structure, its flow-distribution mechanism is an independent design with turnover oil pipe linkage, the size and the weight of rig have not only been increased, and, in use be difficult for controlling because parts relatively disperse.
The utility model content
At the shortcoming that above-mentioned prior art exists, the utility model provides a kind of and guaranteeing the rig speed of gyration steadily on the basis of control, and is simple and compact for structure, size is little, lightweight hand-held mining-drilling machine hydraulic control.
The technical solution adopted in the utility model is: a kind of hand-held mining-drilling machine hydraulic control, comprise toroidal shell, the oil-feed end cap, the compensation side plate, the oil-feed control valve, operating grip, described oil-feed end cap and operating grip are fixed on the toroidal shell, oil-feed end cap and described compensation side plate are fixed together, between oil-feed end cap and compensation side plate, form annular flow duct, the oil-feed duct is arranged in this annular flow duct, side compensation side plate upper edge, this oil-feed duct communicates with the drill motor working chamber, and the drill motor oil back chamber communicates with fuel-displaced duct on being arranged on opposite side compensation side plate.Cover at described oil inlet end and to be provided with the oil-feed control valve that is connected with inflow pipeline, operating grip is by operating described oil-feed control valve with the joining leverage of operating grip.
Described control valve can comprise valve body, is provided with cone valve in valve body, and is provided with valve core reseting spring in the valve body that cone valve links to each other.
Described oil-feed end cap can be connected and fixed by adjusting screw and toroidal shell.
The utility model is different from the mode that other similar mechanism is characterised in that the oil-feed duct is arranged along the annular distributor port road that oil inlet end covers in operating mechanism's one side, because the oil-feed control valve of rig, the mechanism of these control rig work of operating grip and the working chamber and the turnover oil-piping of rig are arranged, make working media enter the rig working chamber by annular distributor port road, and flow out from the operating mechanism opposite side, make the drill configuration compactness, be beneficial to and control.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises toroidal shell 1, oil-feed end cap 2, compensation side plate 4, oil-feed control valve 12, operating grip 8, operating grip 8 is fixed on the toroidal shell 1, oil-feed end cap 2 is fixed on the toroidal shell 1 by adjustment screw 9, oil-feed end cap 2 is connected with compensation side plate 4, between oil-feed end cap 2 and compensation side plate 4, formed the annular flow duct 3 that is communicated with motor 13 working chambers, compensation side plate 4 is provided with oil-feed duct 5, this oil-feed duct 5 is connected with fuel-displaced duct 6 on being arranged on compensation side plate 4 opposite sides, the oil control valve 12 that is connected with oil-feed duct 5 is fixed on the oil-feed end cap 2, and be arranged in parallel with operating grip 8, operating grip 8 is operated control by 11 pairs of oil control valves 12 of lever.
Adjustment screw 9 can play the effect of location, and this screw can screw in certain-length as required, makes oil control valve 12 and operating grip 8 realize being arranged in parallel.
Oil control valve 12 comprises cone valve 7 and the valve core reseting spring 10 that is arranged in the valve body, valve core reseting spring 10 is connected with cone valve 7, when lever 11 actions that are installed on the operating grip 8, cone valve 7 and valve core reseting spring 10 move simultaneously, open control valve 12, working media flows into oil inlet passage, increase area of passage gradually by the valve core reseting spring 10 of compression arrangement then in valve cone 7 back, working media enters the rig working chamber by ring-like distributor port road 3, and flows out from the fuel-displaced duct 6 of work opposite side.
This structural configuration, make the drill configuration compactness, be easy to control, do not have unnecessary connection element and oil pipe, realized the steady control of rig speed of gyration simultaneously.
Claims (3)
1, a kind of hand-held mining-drilling machine hydraulic control, comprise toroidal shell, the oil-feed end cap, the compensation side plate, the oil-feed control valve, operating grip, it is characterized in that: described oil-feed end cap and operating grip are fixed on the toroidal shell, oil-feed end cap and described compensation side plate are fixed together, between oil-feed end cap and compensation side plate, form annular flow duct, the oil-feed duct is arranged in this annular flow duct, side compensation side plate upper edge, this oil-feed duct communicates with the drill motor working chamber, and the drill motor oil back chamber communicates with fuel-displaced duct on being arranged on opposite side compensation side plate, cover at described oil inlet end and to be provided with the oil-feed control valve that is connected with inflow pipeline, operating grip is by operating described oil-feed control valve with the joining leverage of operating grip.
